Steve Dunne had big shoes to fill when he was cast as Sam Spade. Dashiell Hammett's private eye had been thrilling listeners since 1946 in weekly adventures starring Howard Duff, but accusations of Communist sympathies cost Duff the gig. Dunne played a younger-sounding, less serious Sam for the final run of episodes. We'll hear two of them - "The Soap Opera Caper" (originally aired on NBC on February 16, 1951) and "The Sinister Siren Caper" (originally aired on NBC on March 16, 1951). Plus, we'll hear him as crime-solving reporter Lucky Larson in Deadline Mystery (originally aired on ABC on August 10, 1947).
